如何显示cakephp 2.5.3模型验证消息。默认情况下，它显示HTML5验证消息

如何显示CakePHP模型中定义的验证消息。当我提交表单时，CakePHP模型验证工作。但是输入字段的验证消息不显示。它显示HTML5验证消息。我想显示CakePHP模型验证消息。我正在使用CakePHP2.5.3

以下是我的代码块：

控制器：

$this->User->set($this->request->data);
    if ($this->User->validates()) {
        if ($this->User->save($this->request->data)) {
            $Email->send();
            $this->Session->setFlash(__('The user has been created'));
            if ($this->Auth->login()) {

                $this->Session->setFlash(__('Welcome, ' . $this->Auth->user('username')));
                $this->redirect($this->Auth->redirectUrl());
            }
        } else {
            $this->Session->setFlash(__('The user could not be created. Please, try again.'));
        }
    }

型号：

public $validate = array(
    'username' => array(
        'nonEmpty' => array(
            'rule' => array('notEmpty'),
            'message' => 'A username is required',
            'allowEmpty' => false
        ),
        'unique' => array(
            'rule' => array('isUniqueUsername'),
            'message' => 'This username is already in use'
        ),
        'alphaNumericDashUnderscore' => array(
            'rule' => array('alphaNumericDashUnderscore'),
            'message' => 'Username can only be letters, numbers and underscores'
        ),
    )

您不需要在save调用周围包装验证块

这就足够了：

    if ($this->User->save($this->request->data)) {
        $Email->send();
        $this->Session->setFlash(__('The user has been created'));
        if ($this->Auth->login()) {

            $this->Session->setFlash(__('Welcome, ' . $this->Auth->user('username')));
            $this->redirect($this->Auth->redirectUrl());
        }
    } else {
        $this->Session->setFlash(__('The user could not be created. Please, try again.'));
    }

CakePHP在调用Model->save时自动处理验证，并在输入字段下显示错误。因此，如果$this->save由于验证错误而失败，cakephp会将模型验证数组中的消息文本添加到右侧输入字段下。

剩下两个选项：

或者不要在客户端验证的cakePHP中使用验证规则

在DOM ready上，调用$formId.removeAttr'novalidate'；像

$document.readyfunction{ $formId.removeAttr'novalidate'； };

可能的副本，请考虑使用搜索功能或谷歌下一次这种琐碎的问题。请参阅上面帖子中的链接答案。

    if ($this->User->save($this->request->data)) {
        $Email->send();
        $this->Session->setFlash(__('The user has been created'));
        if ($this->Auth->login()) {

            $this->Session->setFlash(__('Welcome, ' . $this->Auth->user('username')));
            $this->redirect($this->Auth->redirectUrl());
        }
    } else {
        $this->Session->setFlash(__('The user could not be created. Please, try again.'));
    }
